other lire-i esisting material, inade in one piece or in sections, and extend throughout the eutirewidth of the kiln, except where a ire or partition-wall is employed in thecentcr of the kiln. 'Ihese perforated pipes` may,`however, be placed under the tire-bed intthe. fire-arches, to promote combustion, as shown in dotted lines in Fig.` l.

For the more accurate and uniform burning` of the brick, I employ `a series of perforated air-pipes, one within the other, or any desired number nested or telescopically arranged, as shown in Fig. 3 and at A in Fig. 2. The outer or larger one of these pipes, a, extends inward a short distance-. say one-third the width of the kiln or one-third the distance of the lire or partition wall. The next pipe, b, extends a short distance farther inward, while the next section, b', may extend to the opposite side of the kiln, as shown at B, or to the wall or abutmentin the center' of the kiln ,.as shown at C', Fig. 2.

The advantages of this mode of construction are obvious, as it enables the operator to direct the air-currents to the fuel at any desired point in the fire-arches, to increase or diminish the heat as may be desired, and insure a uniform burning ofthe entire kiln, which is a very important consideration in view of the fact that To all whom it may concern:

Beit known that I, E. NYE Hnronrson, a citizen of the United States, residing at Ohar lotte, North Carolina, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements -iu Brick-Kilns; and I do declare the following` to be a ful1,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same,.reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My present invention is designed as an Patent numbered 220,213, fith October, 1579, and 246,997, 13th September, 188i, for kilns for burning brick; and to this end my invention consists in providing the air-supplying dues with perforated f air to the lire-arches or combustionchambers, and in the arrangc` ment of said pipes Vso that air may be supplied or suppressed in any desired part of the kiln to promote or retard combustion, as maybe found expedient or desirable. v p

Referring to the drawin gs, Figure l is a vertical longitudinal section on the line x Fig. 2. Fig. 2 is a horizontal sectional view on the line y y of Fig. l. Fig; 3 is a sectional view of a series of airsuppIying perforated pipes, placed one within the other, for controlling the dmission of air into any desired portion of the iln. i

A designates the tire-arches, which are by preference made to extend from one side of the kiln to the other; but, if desired, they may only extend to a rire-wall built across the center of the kiln.

B are the air dues or passages, which may or may not extend across the entire width of brick are too much burned, burned enough, and

amount of air to the larger or outer pipes and to the outer edges or sidesof the kiln. If the natural draft is not sufficient, air may be supplied to all or to any desired number ot' pipes by a blower or other suitable device. 'Ihe material which forms the sides of the nre-arches or air iiues may be of iron, othermetal, fireclay, or other dre-resisting material, and constitute a permanent bench for the kiln, so that ings C, which enter the tire-arches at intervals and at right angles thereto. This construc-` tion so far is substantially the same as the construction in the patents above referred to.

Within the air-fines, according to my present invention, I place perforated pipes D, the perforations registering wit-l1 the lateral air iiues or openings O. These perforated pipes terra-cotta, or iron, or

closing the ends ofthe pipes will direct agreater I in most of the devices now employed in burnthe pipes will remain permanent. The kiln, 2.
